Title: Improvements in weft detector arrangements for looms
IPC: D03D51/34
Filed: 1951-03-09
Abstract: 691,022. Weft feeler arrangement for looms. HANDLER, F. March 9, 1951, No. 5716/51. Class 142(iii) A weft feeler arrangement comprises a plunger i that engages the shuttle box and a feeler a that engages the bobbin. At each beat-up the plunger i is moved by the shuttle box and its end i<SP>1</SP> rocks a lever f about a pivot g. The lever f then moves a member d. When weft replenishment is not necessary, the feeler a engages the weft in the shuttle and moves the member d before the latter is moved by the plunger i and a lever n pivoted at n<SP>1</SP> is not moved. If weft replenishment is necessary, the plunger i moves the member d before the latter is depressed and, when the feeler a subsequently engages the almost depleted bobbin, the member d is pressed on to a lug m, the lever n is turned, a link o is moved, and the loom stopped or replenishing mechanism actuated. If the loom is to be stopped, the link o moves a rod to a position where it is engaged by the moving weft hammer. This rod may have a lever attached that knocks off the starting handle, alternatively, the rod may be attached to the usual rod that is moved, when the weft fork engages its hammer, to stop the loom. The cloth takeup may be put out of action.

Filed: 1925-03-03
Abstract: 230,815. Guillet, A. V. J. March 15, 1924, [Convention date]. Addition to 213,233. Stroboscopic apparatus. - The invention described in the parent Specification is modified by replacing the shutter on the vibrating cord by a contact piece which at each vibration of the cord interrupts the current in the primary circuit of an induction coil or the like arranged to feed a condenser and thus to give. a condensed spark. In place of the condenser a Neon tube. of large surface may be used so that large areas may be illuminated. In the middle of the cord a of the stroboscope, which is stretched horizontally, a light metal wire. m in the form of a bridge is fitted, the ends of the bridge dipping into two compartments in a vessel of insulating material containing mercury. The circuit n<3> which is broken when the shorter of the two arms leaves the mercury contains an induction coil n<4>. In a modification the make and break may be effected by the torsional movement of the cord. In this case a pallet attached to the cord is operated by an electromagnet to make and break the circuit. Variation in frequency is produced by adjustable masses on the pallet or bv varying the length of the cord. For the production of low frequencies a stroboscope with two cords provided with shutters is used, the slots in the shutters coinciding with the slots in a fixed shutter. The cords are stretched so as to produce slightly differing frequencies.
